These files are only writable by root, hence nginx worker
processes won't be able to open these for writing after log
rotation. You have to fix your log rotation configuration to
create files which are writable by nginx user.

For example, nginx own packages as available from nginx.org use
the following logrotate configuration
(http://hg.nginx.org/pkg-oss/file/tip/debian/nginx.logrotate):

/var/log/nginx/*.log {
daily
missingok
rotate 52
compress
delaycompress
notifempty
create 640 nginx adm
sharedscripts
postrotate
if [ -f /var/run/nginx.pid ]; then
kill -USR1 `cat /var/run/nginx.pid`
fi
endscript
}

Note the "create 640 nginx adm" line.
